Flashrom error on apu2

rossomonza · 12 June 2023 13:42

Hi all,

getting an error on apu2 board while updating the fw to 4.19.0.1. The same after rebooting ipfire.
What could be the culprit?

The specific error flashrom: symbol lookup error: flashrom: undefined symbol: pci_filter_init, version LIBPCI_3.3 is saying that the flashrom program is trying to use a function called pci_filter_init from a library related to the PCI subsystem, but it can’t find this function.

This is the first time I encounter this problem. Did you manage to update the firmware before?

@ms can this be an IPFire build problem?

rossomonza · 13 June 2023 06:03

Before 175 no issues updating the apu2 fw.
If this is not a build problem i do scratch install ipfire. No problem.

pciutils was updated from version 3.8.0 to 3.9.0 and the updated library was shipped with CU175.

I just ran ldd on flashrom in CU174 and CU175 and the libraries are linked to the same file in both cases.
libpci.so.3

Try running the following command on your C175 system

ldd /usr/sbin/flashrom

In terms of the library file links it should be the same as what I just found

linux-vdso.so.1 (0x00007fff93990000)
libpci.so.3 => /lib/libpci.so.3 (0x00007a2469992000)
libusb-1.0.so.0 => /usr/lib/libusb-1.0.so.0 (0x00007a2469972000)
libc.so.6 => /lib/libc.so.6 (0x00007a246978c000)
libresolv.so.2 => /lib/libresolv.so.2 (0x00007a246977a000)
libudev.so.1 => /lib/libudev.so.1 (0x00007a2469752000)
libatomic.so.1 => /usr/lib/…/lib64/libatomic.so.1 (0x00007a2469748000)
/lib64/ld-linux-x86-64.so.2 (0x00007a24699be000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007a246972c000)

If the libpci.so.3 link is missing then something went wrong during the upgrade.

If all the links are the same then I don’t understand what is happening.

I did the upgrade to that version on my apu4 on CU174 and everything went without a hitch and the library links are the same as the above ones for CU175.

The symlink for libpci.so.3 to libpci.so.3.9.0 can be checked as follows:-

ls -hal /lib/libpci.so.3*
lrwxrwxrwx 1 root root 15 Jun 9 21:13 /lib/libpci.so.3 → libpci.so.3.9.0
-rwxr-xr-x 1 root root 140K Jun 9 22:27 /lib/libpci.so.3.9.0

This shows that the new library, libpci.so.3.9.0 is on the system and libpci.so.3 is symlinked to it.

Does your system show the same?

7 posts were split to a new topic: Why i have there such a number in APU BIOS?

rossomonza · 13 June 2023 16:35

As mentioned a scratch install of CU175 solved the issue.

Thank you for your time spent.

My system shows the same as above but i cannot upgrade with flashrom anymore - at least not from my

Board       : PC Engines apu4
HW Version  : 1.0
...
BIOS Version: v4.16.0.4 (05/25/2022)

I get the same error message as Nils:

-rwxr-xr-x 1 root root 140K Jun 12 18:29 /lib/libpci.so.3.9.0

So the only solution is to reinstall from scratch ?

bonnietwin · 16 June 2023 13:22

Your best choice may be to re-install version Core Update 174 and then do the firmware-update and then do the core update to 175.

There does look to be a problem with the pciutils package version 3.9.0

Fedora have found a problem with the cpupower package that is caused by the pciutils package and having the same error message as you and @rossomonza reported.

Fedora apparently made some changes to their pciutils install to make things work but currently I can’t access the fedorproject.org site at all. I keep getting:-

The connection has timed out

An error occurred during a connection to fedoraproject.org. PR_IO_TIMEOUT_ERROR

Error code: PR_IO_TIMEOUT_ERROR

Any fix will require a new compile build to make pciutils work and so will end up in CU176. Hence my suggestion to re-install CU174 and then do the apu firmware update.

bonnietwin · 16 June 2023 15:07

My inability to access the fedoraproject.org sites was something to do with the IPFire Proxy. I changed my browser to use the system proxy and sites are accessible now.

Anyway, found the patch that Fedora have used for pciutils-3.9.0 to fix the problem of some symbols not being made available.

However version pciutils-3.10.0 has been released and Fedora have installed that and it doesn’t need the extra patch anymore as they have removed it. So I will submit an update patch for pciutils-3.10.0

Your quickest solution will still be to re-install CU174, do the firmware update then upgrade to CU175.

After APU BIOS version 4.19.0.1 I think it will be a long time, if at all, before another BIOS update is issued.

ok, thx for your ideas.

Maybe i will then wait for a 176 with corrected pciutils pkg - I did not reinstall from scratch yet (the setup of the Huawei 600VE modem was a bit tricky) and so far everything else runs smoothly.

With the GX-412TC EOL the FW will probably have to move to a new SOC anyway.

That’s sad, it was a very good platform for ipfire.
